Affiliate disclosure. The partner link in the masthead and beside the copy on this page is a sponsored link to a partner operator, and this site may be paid if you open an account through it, at no extra cost to you. It carries rel="sponsored noopener" and opens in a new tab. Nothing about that payment depends on what is written here: these pages contain no ranking, no review and no recommendation of any operator, studio or game, no prediction and no “system”, and no claim that any product is available in your territory. Explaining how a game is supplied, certified and identified is not advice to play it — a game whose build is certified and correctly identified still loses money at its stated rate.
Game Shelf / Certification
What a laboratory examines

What certification covers

A certificate is a statement about a specific build of a specific title, made against a written specification, for a specific market. Knowing what is inside that statement — and what is outside it — is what makes the certificate useful.

Direct answerAn approved laboratory examines a build: that its random process is unpredictable in the way the specification requires, and that its paytable and returns match the specification it was submitted with. Certification belongs to that build in that market — it says nothing about the operator, your session or your outcome.

Four things a certificate is about

What is examined, in the terms the market\u2019s rules use
ItemThe question answered
The random processDoes the mechanism that decides outcomes produce results that cannot be predicted from earlier results?
The paytable arithmeticDo the published pays and probabilities produce the return the specification claims?
The build itselfIs the software that will be delivered the software that was tested, and can the delivered version be checked against it?
The market\u2019s requirementsDoes the build meet the local rules on display, stakes, limits and information?

Per build, not per name

The single most useful thing to understand about certification is its unit: the build. A title is a name; a build is a version of it. When a supplier changes the maths or adds a feature that changes outcomes, the artefact changes, and a statement about the previous artefact no longer describes the new one.

This is why the phrase “the game is audited” is not a complete answer to anything. The useful question is which build, examined against what, for which market — and the help panel is where the build identifies itself.

What a certificate cannot do

It is worth being precise, because the limits are where readers get misled.

a certificate is about the build, not about the operator
it is about the long-run arithmetic, not about your session: £1,000 staked at 96% returns £960 in expectation, with an enormous spread over any short run
it is about compliance with a specification, not about whether a game is enjoyable, suitable or affordable for you
it is about a market, not about every market: the same studio may run different builds and different configurations in different regulated territories

None of that is a criticism of certification. It is what certification is for: a narrow, checkable statement about one artefact, which is exactly why it is worth more than a general claim that a game is “fair”.
